Next, this setup requires an External Authorization Filter in the Envoy configuration that connects to the new service. The following table lists the most common gRPC status codes that you might see, their causes, and their resolutions. I imagine that the error may very well lie with me and my config rather than with Envoy but I can't seem to find a way around this and so am reporting it. In this example, we will use the Envoy proxy to forward the gRPC browser request to the backend server. Envoy currently only supports passing this as a file path or passing a whole string on the command line with --config-yaml. Helping dev teams adopt new technologies and practices.
